Incidence, risk factors and impact on virological response of anemia in chronic genotype 2 hepatitis C receiving sofosbuvir plus ribavirin

Background/Purpose: The major dose-limiting toxicity of ribavirin is hemolytic anemia. We investigated the incidence, risk factors and impact on virological response of anemia in chronic hepatitis C genotype 2 patients receiving sofosbuvir plus ribavirin therapy. Methods: This was a retrospective real-world analysis of a single center including 293 chronic hepatitis C genotype 2 patients treated with sofosbuvir plus ribavirin for 12 weeks.
